Radiative cooling is a phenomenon that allows people to make ice in the dessert on a clear night, but practical uses in our modern world have been limited — primarily because it’s most useful at night. Aaswath Raman and his team of researchers are using nanotechnology to create a material that reflects solar radiation and disrupts thermal heat enough to make radiative cooling possible during the day. It’s an incredibly elegant solution to how to keep materials cool without using mechanics or electricity. They’ve commercialized the tech into a way to make air conditioners more efficient.
I genuinely love solutions like this to the biggest problem we face as a planet. It’s innovative, cheap, works with existing systems, and doesn’t require some massive sacrifice. When I see how these small changes can add up, it give me hope, as well as infuriates me that we waste so much time arguing over whether climate change is even a problem worth addressing instead of getting to the urgent work of making the world a better place.
One of Facebook’s more salient and successful qualities is the ability to see where things are headed in a big picture sense — perhaps that’s generous, or perhaps it’s what you’d expect from the most pervasive panopticon ever created. They realized early on normal people don’t care about things like privacy online and exploited that to their maximum advantage, for example. It made them wildly successful and largely unassailable.
They’ve finally looked into the fetid swamp of QAnon and decided that being a vector for this insane malignancy of a truly mad age is not a great look. Only three years too late and after this dark conspiracy has become an untamable Lovecraftian horror. But they see there’s a political, if not necessarily cultural, shift and playing along with Trumpism no longer seems like a winning game. Their cowardice and irresponsiblity will haunt us for a long long time.
